JOSEPH H. GLAUBER, OF CLEVELAND, OHIO.

BASIN, BATH-COCK, AND OTHER PLUMBING CONNECTION.

To all whom it may concern:

Be it known that I, Josnrrr H. GLAUBER, citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Basin, Bath- Cock, and other Plumbing Connections, of which the following is a specification.

My invention relates to basin, bath cock, and other plumbing connections, and comprises an improved coupling member having a hollow metallic tapering head substantially as herein shown and described and more particularly pointed out in the claims.

Briefly reviewing present conditions, I am aware of the existence of coupling members having solid tapering heads, and also others which are provided with separate removable cone-shaped gaskets of solid rubher, lead or the like. Now in actual practice it is not always permissible or practicable to use solid rubber gaskets or separate solid gaskets of any kind, as builders specifications or some particularneed demand an integral construction and metal to metal seatmg of the coupling membersyand therefore the cou ling members'having unyielding heads oi solid metal have heretofore been specified and employed. These solid metal heads are of varying tapers but the practice 18 to mate them with the tapered seats in the shanks of bath or basin cocks, which shanks are generally made of cast metal. In view of these facts and that different parts of the coupling are sold as separate articles of manufacture by many different manufacturers-consequently varying materially in size, form and construction-imperfect and detective connections are often the result. One serious trouble met with by plumbers is the splitting of the tapered end of the cast shanks and resultant leakage when a tapered solid-metal head is drawn up too tightly therein. Stripping of the threads on the outside of the shanklor in the coupling-nut is also a constant occurrence, particularly when too great a seating resistance is offered during coupling operations.

Now, therefore, my object is to provide a coupling member in which all the strength, durability, ermanency and advantage of a solid metal ic coupling head is combined with all the flexibility and universal applicability of a rubber or other yielding gasket; but eliminating the disadvantages and Specification of Letters Patent.

objectionable features of both constructions as made and used heretofore.

In other words, I aim to meet a pressing and evergrowing need by furnishing the trade and the public with a coupling member having a hollow tapered metallic head particularly constructed to yield under pressure without rupture so as to conform with the different beveled seats of the shanks of different manufacturers. Splitting of the shank-end and stripping of the threads is thereby prevented and any variation between difi'erent makes of coupling members is also taken up,making a perfectly secure and eflicient fluid-tight connection adapted to withstand a high test without the aid of gaskets of any description and giving a wide range of service with any kind of fluid hot, or cold, chemical, gaseous, or those deleterious in quality or action. Simplicity of construction -anddurability are in fact marked features of my improved coupling member.

In the accompanying drawings, Figure l is a sectional elevation of one form of my [improved couplingmember attached to a loath-cock shank showin the hollow head contracted to conform with the tapered seat in theshank, and Fig. 2 is an enlarged sectional view illustratin the relation of. the partsand form of tlie head before contraction takes place.

Now referring to Fig. 1, tubular member 52 shown there1n:represents one form of bath-cock shank in general use, and this shank 2 rojects. through an opening 3 in wall 4 0? the bathtub and is fastened in place by ,a nickel-plated screw flange 5 10- cated u on the inside of the tub and byta detacha le screw collar 6 on the outside. The faucet or cock (not shown) is secured to member 2 by nut? engaged with end flange 8, and the o posits end of the shank member is tapere Internally to provide a flaring seat 9 for a conical sealing head A either integral with or a separate fixed part of a tubular body 10. These two parts taken together constitute a single unitary coupling member B adapted to be sold as a se arate article of manufacture for use witi the Ishank described or with an equivalent mem- In practice, head A is detachably connected with the shank, and the op osite end of coupling member B is attac ed either adjustably, detachably, or permanently-to a supply or service pipe more or less distantly located from the shank. Therefore, body 10 is preferably made of bendable metal to permit hand bending and deflection of coupling member B in making attachments-head A, however, always sustaining axial alinement with shank 2. This form of an all-metal coupling member A is shown in Fig. 1, wherein the walls of both body 10 and head A are of uniform thickness and annealed to give the required eflects. In fact, coupling member B is preferably made of drawn tubing, annealed throughout, to provide a yieldable contractible cone head A and a bendable stem or body 10,a one piece construction without joints end to end.

As shown in Figs. 1 and 2, head A is ta pered and hollow, or conical, and its truncated end is approximately of the same diameter as body 10. The enlarged portion of head A is formed by developing an annular shoulder 11 about body 10 at right angles to the axis thereof, and this shoulder is stiffened or braced by the taperingl wall of the cone where merged therewit at the bend, makin a strong and rigid thrustbearing for anged couplin nut 12 wherewith draw connection is ma e with shank 2. The taper of head A, is preferably on more acute lines than the average taper found in seat 9 of the shanks in general use, which difference in construction causes an initial seating engagement forwardly on the head when it is first introduced into the shank. In this relationship the tapered seat 9 in the shank at the be 'nning of operations is also engaged inwar ly at its sma lest diameter opposite the thickest or heaviest portion of the shank-end (see Fig. 2,) and therefore, when cou lin nut 11 is screwed up head A will be orcibly carried forward and contracted to conform to the taper of seat 9 (see Fig. 1). This result would not readily follow unless head A was conical and made of ductile metal; nor would such seating always result without rupture of head A or splitting of the shank-end if both parts were solid and unyielding In ex anding operations to form head integra ly wit body 10 the walls of said head may become thinner, but this is of advantage rather than otherwise as head A is particularly designed to have more yield and ive than the body. In fact, if heavy meta is used, the ta ering wall of the head may be materially re uced in thicknesses by lathe or other operations. On the other hand, total collapse of head A is also a contingency to be considered, walls of very thin material being impracticable for this reason. In this connection it must also be remembered that coupling member B is subjected to internal pressures, and that body 10 must necessarily be heav 'enough to meet these requirements,

articu arly between its ends where not remforced or inclosed by other parts. Initial engagement between conical seat 9 and cone head A where truncated assists materially in preventing s litting of the shank-end because the thic est or heaviest portion of said shank is first to bear the brunt of the compressive strains, and for the further reason that head A will be the first to yield-being made of lighter or of softer material than the shank which is generally of cast metal. The best of sealing effects is also obtained by this-combination of a conical head made of tough, tenacious and yieldable metal, with a tapered shank-end of cast metal, as any roughness or irregularity in the harder metal will be accommodated in the softer and more pliable one.

Tubular body 10 of coupling member B is shown of the same diameter throughout, although this is optional in view of known forms having different diameters, particularly at opposite ends. Many coupling members are of the form illnstrated-bent at right an les with straight short and long stems. gome are straight end to end,- others have a double bend therein; but inasmuch as these features are old and well known and do not afi'ect my invention, further disclosure and reference thereto is omitted.'

WhatI claim is:

1. As a new article of manufacture and sale, a tubular couplin pipe of pliant metal having an acute-ang ed truncated head formed from the wall thereof at one end, said head being of relatively greater diameter thanthe pipe to form a right-angled shoulder for a union nut and having a converging portion of uniform thickness extending on straight lines at an angle of approximately twenty two and one-half degrees to the axis of the pipe from the outside diameter of said shoulder to a smaller diameter than the smallest internal diameter of the inner edge of the tapered seat of the cast metal faucet shanks in general use so as to provide an initial seating engagement of the truncated portion of the head with said edge at a point directly opposite the thick portion of the shank end.

2. In] a plumbing connection adapted to be used between a service pipe and a faucet, a tubular shank havin an internall -tapered end providing a aring seat wit an annular sharp edge inwardly from its extremity, in combination with a tubular coupling member having separate coupling ends, one of which comprises a hollow truncated acute-angled cone having a right-anled base wall to provide an annular angu- .ar shoulder about said member and a s1de wall of substantially uniform thickness converging forwardly on straight lines at an angle of approximately twenty-two and onehalf degrees to the axis of sa1d member and providing a yieldin body of greater diameter than said tu ular member and of extended length and of smaller diameter at its end than said shank internally at the inner sharp ed e of its tapering seat, and means to forci% member togethen 3. In a plumbing connection, the combination of a tubular threaded shank for a faucet or other water distributing device, having an internal flaring seat at one end, and a union nut, with a coupling tube for a service pipe, made of pliant metal with one end thereof expanded to a relatively greater diameter in the form of an annular right-angled shoulder and an annular converging portion of substantially uniform thickness extending on straight lines. externally and internally from the outer porly couple said shank and tion of said shoulder to a smaller diameter of relatively the same diameter as said tube, the degree of angle of said converging ortion being relatively acute to the axis 0 the pipe and said portion being also relatively long to make an initial seating engagement with said flaring shank seat inwardly from its extremity and providing a contractible extension to permit the said coupling tube end to project into the main bore of said shank beyond the smallest diameter of said flaring seat when the parts are coupled together with the union nut screwed to its limit.
